Nonsingular parametric oscillators Darboux-related to the classical
harmonic oscillator    [PDF]

H. C. Rosu, O. Cornejo-Perez, P. Chen

Interesting nonsingular parametric oscillators which are Darboux related to the classical harmonic oscillator and have periodic dissipative/gain features are identified through a modified factorization method. The same method is applied to the upside-down (hyperbolic) `oscillator' for which the obtained Darboux partners show overdamped features
